Waterproof 20L Dry Bag Backpack — 500D PVC, roll-top seal, adjustable double shoulder straps Key benefits Reliable waterproof protection: 500D PVC material and a roll-top closure create an impenetrable barrier against water, keeping clothing, electronics and important gear dry in wet conditions. Big enough for day trips: 20 litres of space holds a change of clothes, food, water bottle and camera gear while remaining compact and easy to carry. Built for rough use: reinforced stitching and heavy-duty construction resist abrasion, sand and impact so the bag survives tough trails and repeated use. Comfortable to carry: adjustable double shoulder straps distribute weight evenly, provide ergonomic support and include ventilated padding to reduce heat and pressure on long hikes. How it works Roll-top closure: roll the top tightly 3–4 times and secure the buckle to form a watertight seal. This simple system prevents water ingress while keeping contents organized and accessible. Durable construction: 500D PVC resists punctures, tears and saltwater. Reinforced seams and strong buckles extend service life in demanding outdoor environments. Carry system: twin adjustable shoulder straps allow a balanced fit and improved comfort for long days on the move. What fits Capacity: 20L — fits a full change of clothes, lunch, a 1L water bottle, small camera or compact rain jacket and other day-ride essentials without excess bulk. Practical use scenarios Kayaking or rafting: keeps clothing, electronics and camera gear dry during paddling and in splash-prone situations. Day hikes in variable weather: protects layers and food from sudden rain or stream crossings while remaining comfortable on the trail. Beach, fishing or boating trips: blocks sand and saltwater, making it easy to carry valuables and spare clothes safely.
